a Chemical structures of αCD host and AzoC6 guest molecules. The corresponding hydrogens for NMR spectra are also denoted. b 1H NMR spectra (400 MHz, D2O, 298 K) of 1-methyl-3-(5-(4-(phenyldiazenyl)phenoxy)pentyl)−1H-imidazol-3-ium (AzoC6), alpha-cyclodextrin (αCD), and AzoC6/αCD complex (1:2 ratio). Light-responsive phase behavior of (c) 50 mM AzoC6@2αCD and (d) 30 wt% MXenegel under UV and visible light irradiations. The irradiation times of UV and visible light are 10 and 30 min, respectively.
